6 Reasons Why Your Air Conditioner isn’t Cooling Properly

During searing summers, nothing could be worse than finding out that your AC isn’t operating well. This would be the last thing you want to hear!

You need to know that your air conditioner is an exceptionally intricate system, making it difficult to determine what’s creating the trouble. Hiring a reliable and experienced air conditioning service provider would make it easier for you in identifying reasons related to what’s wrong with your air conditioner. They can also guide you on how to fix the issues.

Your air conditioner should cool well in order to get the temperatures down to comfortable levels. Usually, AC systems have five components:

  • fan
  • evaporator coil (cools the air)
  • compressor (electric pump)
  • condenser coil (transfers heat)
  • expansion device

Primarily every unit has two parts: one is inside your home, and the other is outside.

The fan present in the inside unit blows air through the chilled evaporator coil via the air ducts. The unit place outside, the compressor, condenser coil, and another fan throws away hot air coming out of the refrigerator.

The expansion valve manages the refrigerant moving between the evaporator and condenser coils.

Any mechanical failure in the above components means you need to call a trained technician right away! All your appliances should be maintained and replaced regularly, especially before the summer. Rely on a professional air conditioning service provider!

There a few common facts you need to know why your AC may not be cooling properly:

  1. Poor maintenance

To ensure optimal function and the long life of your AC, you need to maintain it by a professional periodically.

Routine check-ups can prevent technical troubles such as, refrigerant leakages, compressor damage, or condenser coil faults that should be repaired immediately. Irregular maintenance can directly contribute to an underperforming AC 

  1. Direct sunlight on AC outdoor unit

People don’t realize and install their AC directly facing the sun. In the case of split AC or window AC, direct sunlight can affect the efficiency of your AC. All ACs have an optimum operating temperature that allows smooth functioning.

If the temperature increases beyond the optimum temperature, the efficiency of the air conditioner goes down, and it can also reach a stage where the compressor will stop working completely.

In this case, your unit is likely to consume more electricity than expected. Routine air conditioner maintenance is a must!

  1. Improper setting of the thermostat

People tend to use their thermostat differently as per their needs. Many people make the mistake of setting their device to ‘ON’ instead of placing it in ‘AUTO’ mode.

With this setting, the fan will produce an air current even after your room has achieved the desired temperature. Try to adjust your settings accordingly.

  1. Dirty air filters and condenser coils

These two components negatively impact the ability of your AC to cool properly. Dirt and grime accumulated on the filter and coils trap heat and restrict airflow. This leads the unit to overheat and results in inefficiency.

For a dirty or clogged condenser, you need to do some landscaping around it. It includes: 

  • Dense vegetation will interfere with heat dissipation, making it difficult to perform properly.
  • Create 18 inches of clear space on all sides.
  • Invest in a protective cover for your condenser to prevent damage.

For dirty or clogged air filter, consider the following: 

  • Regular cleaning and replacing is mandatory
  • Change your air filter once every 12 months
  • Check your air filter every 30 days to prevent clogging

Always rely on a professional technician to help you with air conditioner maintenance.

  1. Is your AC releasing refrigerant?

Do you experience a lack of cool air, more expensive power bills, frozen evaporator coils, and strange hissing noises arising from your HVAC?

This means there is a break somewhere, and there is a substance (refrigerant) leaking.

Refrigerant is a substance that chills the air in your house and cycles between your indoor and outdoor systems to absorb and release heat. Be quick in calling your technician as it can be detrimental to your family’s health.

  1. Excessively airy rooms

Your AC functions by dehumidifying the area i.e., the existing humid area is run through the evaporator and chemically cooled and circulated. This process is repeated until the room reaches its desired temperature.

Extremely ventilated rooms can hamper the process as the constant air supply will prevent the AC from functioning correctly. Follow regular AC duct repair for smooth functioning.

Follow these simple solutions to enjoy the benefits of your AC, especially during summertime. We know that upgrading your AC can be expensive, but some of the above efforts can help you get a great deal on your current unit.
